The mouth should not be opened widely for at least 6 weeks after dislocation. The jaw should be supported by one or both hands during motions such as yawning and sneezing to prevent excessive strain on the temporomandibular joint.

FRACTURED JAW

The goal of treatment is proper alignment of the jaw bone so the upper and lower teeth come together normally.

Temporary immobilization of the bone by bandaging the jaw (around the top of the head) or immobilizing the jaw with the hands may reduce pain.

If the fracture is minor, no treatment may be required other than analgesics for discomfort and a soft (or liquid) diet to minimize pain while chewing.

Surgery is often required for moderate to severe fractures to align and immobilize the bone so it can heal.

The jaw may be wired to the teeth of the opposite jaw to improve stability. Jaw wires are usually left in place for 6 to 8 weeks. The wires are used to hold metal bands with small blunt hooks (archbars) to the teeth. Small rubber bands (elastics) are used to hold the teeth together. After a few weeks of complete immobilization of the jaw, some of the elastics are removed to allow motion and reduce stiffness of the TMJ.

If the jaw is wired, only liquid or very soft foods can be eaten. Blunt scissors should be available to cut the elastics, so that -- if the person vomits or chokes -- the jaw can be opened to prevent aspiration into the lungs. If the wires must be cut, consult the health care provider promptly so they can be replaced.
